Dutch designer Jolan Van Der Wiel created a public workshop where visitors could make their own colorful trays using natural forces. The designer, famous for creating strange, spiky objects with the help of gravity and magnetic fields, is now harnessing the power of centrifugal forces and a recycled tool he developed himself.

Van Der Wiel mixes plastic with sand, concrete and other elements to give his trays a rigid, textured quality. To make his psychedelic designs, he developed a new, easy to operate machine powered by an old bike crank that spans a table top and creates unique centrifugal designs once in motion.
